Problems solved by technology

Such a period is considered to be too long under current tendency.
This problem cannot be solved by merely reducing the application time of the dyeing compositions since it would be difficult to maintain the same satisfactory levels of coloring in shortened application times.
However, such an option is undesirable, because of the increased risk of degradation of the keratinous substrates.

Low pH Blue Binary Color Deposit Study

[0305]A test swatch of 90% gray hair from IHIP, International Hair Importers, (1 cm width, 15 cm length) was dyed with 20 g of the mixture of the below dye composition mixed 1:1 with L'Oreal Majicreme™ 20 volume developer. The pH of the final mixture was adjusted to 6.5 using NaOH.

Wet Combing Study

[0313]Six untreated IHIP regular bleached hair swatches (1 inch width, 5.5 inch length) were measured for Energy Break (the energy needed to comb through the whole hair swatch), using the Instron wet combing machine. The swatches were then dyed with 15 g of the mixture of the below dye composition mixed 1:1 with L'Oreal Preference™ 20 volume developer.

IngredientsExample 3DI WaterQ.SOleamidopropyl Dimethylamine2.5%PPG-5 Ceteth-2016.0% Oleth-10 Phosphate0.5%Mineral Oil1.0%Resorcinol0.550% p-phenylenediamine0.540% 

[0314]The dyed swatches were measured wet for final Energy Break reading. The average Energy break readings of the untreated and the dyed swatches were 537.40 and 237.58 g-in, respectively. These values are statistically significant. The average percent change in combing is −48.93, therefore the hair is about 49% smoother than before coloring. Thus, the inventive formula gives a better conditioning to the hair.

Abstract

The present invention is drawn to a composition and method for dyeing keratinous substrates containing: (a) at least one fatty monoamine compound; (b) at least one nonionic surfactant; (c) at least one phosphate ester chosen from alkoxylated alkyl phosphate esters and alkyl phosphate esters; (d) at least one dye chosen from oxidation dye precursors and direct dyes. The compositions of the present invention may optionally contain at least one thickening agent, at least one alkaline agent, at least one fatty substance other than a fatty acid, at least one salt, and at least one oxidizing agent.

Description

STATEMENT OF RELATED APPLICATIONS[0001]Not applicable.BACKGROUND OF THE INVENTION[0002]Throughout the years, people have sought to modify the color of their skin, their eyelashes or their hair. Several techniques have been developed to achieve the desired color.[0003]It is known to dye human keratinous substrates, such as the hair, with dye compositions comprising oxidation dye precursors, which are also known as oxidation bases. To vary the shades obtained with these oxidation bases, additional couplers or coloration modifiers may be employed.[0004]It is also known to dye human keratinous substrates by direct dyeing, which comprises applying to the keratinous substrates direct dyes, which are colored.[0005]Traditional application time for dyeing keratinous substrates is around thirty minutes. Such a period is considered to be too long under current tendency.[0006]This problem cannot be solved by merely reducing the application time of the dyeing compositions since it would be diffi...
